Getting rid of the polluting and noxious diesel generators, this battery connected with solar panels and monitor provides clean energy for isolated areas.

My Joule Box brings solar energy through leasing to enable development in rural area in Africa as 600 million of African people do not have access to electricity. This solution consists of an intelligent monitor which operates with solar panels, battery and so on. It works on a wide range of powers (from 50 Wp to 30kWp) in AC or in DC, with the flexibility to evolve according to the needs for the customer, without total replacement of the system. Working only with local companies that create local jobs and skills for a sustainable development, My Joule Box brings financing to their partners for the sale of the systems on credit over 3 years.
